Support résilient à seuil, notamment pour la suspension sur des navires LaThin resilient support, especially for suspension on La vessels
présente invention a trait à un support present invention relates to a support
résilient à seuil destiné à la suspension de tous dispo- resilient threshold intended for the suspension of all provisions
sitifs ou matériels, par exemple appareils ou armoires électroniques, électriques, transformateurs, machines, sur des structures susceptibles d'être soumises à des chocs importants, notamment des navires de guerre, devices or materials, for example electronic or electrical apparatus or cabinets, transformers, machines, on structures liable to be subjected to significant shocks, in particular warships,
par exemple en cas de grenadage.for example in the event of grenading.
On connaît déjà des résilients à seuil desti- Resilient thresholds are already known for

Certains de ces résilients utilisent born to act as normally rigid supports but capable of deforming to absorb the energy of a shock when its importance exceeds a predetermined threshold. Some of these resilients use
un élément fracturable, par exemple une goupille. a fracturable element, for example a pin.
Dans le cas de la suspension sur des navires, le problème se complique du fait qu'un navire peut être soumis à des accélérations importantes et néanmoins normales, par exemple en cas de forte houle. La présente invention se propose donc de fournir un support -2- résilient à seuil, notamment pour la suspension sur navire, qui permette de protéger un dispositif ou In the case of suspension on ships, the problem is complicated by the fact that a ship can be subjected to significant and nevertheless normal accelerations, for example in the event of heavy swell. The present invention therefore proposes to provide a resilient support -2- threshold, especially for suspension on a ship, which allows to protect a device or

Un autre objectif de l'invention est de Another object of the invention is to
fournir un tel support simple, fiable et peu onéreux. provide such a simple, reliable and inexpensive support.
L'invention a pour objet un support résilient à seuil, notamment pour la suspension de dispositifs ou matériels sur des navires, du type comprenant un élément fracturable, caractérisé en ce qu'il comporte The subject of the invention is a resilient threshold support, in particular for the suspension of devices or materials on ships, of the type comprising a fracturable element, characterized in that it comprises
un élément de support en forme de U, en matériau rési- a U-shaped support element, made of resilient material
lient, par exemple en acier doux, dont l'une des branches est fixée sur la structure porteuse, telle link, for example mild steel, one of the branches of which is fixed to the supporting structure, such
qu'un navire, et dont l'autre branche supporte le dispo- than a ship, and the other branch of which supports the provision
sitif ou matériel, les dites deux branches étant rigidi- sitive or material, the two branches being rigidi-
fiées par une entretoise s'étendant entre elles, formée par une tige fracturable dans un plan sensiblement parallèle aux branches du U et reliée aux deux branches, la liaison avec l'une au moins desdites branches étant assurée par un second élément tel qu'une goupille, linked by a spacer extending between them, formed by a fracturable rod in a plane substantially parallel to the branches of the U and connected to the two branches, the connection with at least one of said branches being provided by a second element such as a pin,
fracturable dans la direction de la tige. fracturable in the direction of the stem.
De façon avantageuse, les dimensions desdits éléments et les caractéristiques des matériaux qui les constituent, sont choisies de façon que les fréquences de résonance significatives (c'est-a-dire avec un coefficient d'amplification maximum de 2) sont supérieures à 50 Hz, l'entretoise évitant les fréquences Advantageously, the dimensions of said elements and the characteristics of the materials which constitute them, are chosen so that the significant resonance frequencies (that is to say with a maximum amplification coefficient of 2) are greater than 50 Hz , the spacer avoiding frequencies

Conformément à une caractéristique avantageuse de l'invention, l'entretoise fracturable est reliée aux branches du U par des moyens réglables autorisant le blocage de l'entretoise après installation et blocage - 3 - de la charge, telle que le dispositif ou matériel, sur le U. According to an advantageous characteristic of the invention, the fracturable spacer is connected to the branches of the U by adjustable means allowing the locking of the spacer after installation and locking - 3 - of the load, such as the device or material, on the U.
Ces moyens réglables de blocage sont de préfé- These adjustable locking means are preferably

l'invention apparaîtront & la lecture de la description the invention will appear on reading the description
suivante, faite à tire d'exemple non limitatif, et se référant au dessin annexé dans lequel: - La figure 1 représente une vue en coupe d'un support selon l'invention, - La figure 2 représente une vue en coupe following, taken from a nonlimiting example, and referring to the attached drawing in which: - Figure 1 shows a sectional view of a support according to the invention, - Figure 2 shows a sectional view
du manchon de blocage de ce support. of the locking sleeve of this support.
Le support selon l'invention comporte un élément de support en U, 1, ayant une forme d'étrier, The support according to the invention comprises a U-shaped support element, 1, having a stirrup shape,
dont l'une des branches, 2, est destinée à être appli- one of whose branches, 2, is intended to be applied
quée contre une structure horizontale d'un navire grâce à un trou 3 permettant le boulonnage. L'autre branche, 4, présente un trou similaire 5 pour le boulonnage quée against a horizontal structure of a ship thanks to a hole 3 allowing bolting. The other branch, 4, has a similar hole 5 for bolting
d'un matériel supporté par cette branche. of hardware supported by this branch.
Dans la branche 2 est fixée une douille In branch 2 is fixed a socket
6 émergeant vers l'intérieur du U et recevant l'extré- 6 emerging towards the inside of the U and receiving the end
mité inférieure d'une tige fracturable 7, immobilisée lower part of a fracturable stem 7, immobilized
dans la douille 6 par une goupille fracturable 8 s'éten- in the socket 6 by a fracturable pin 8 extends
dant transversalement à travers la tige 7 et la paroi circulaire de la douille 6. Une gorge d'affaiblissement -4 9 est pratiquée dans la tige 7 de façon a provoquer la rupture sous l'effet d'une accélération horizontale supérieure à un seuil déterminé, par exemple compris dant transversely through the rod 7 and the circular wall of the sleeve 6. A weakening groove -4 9 is formed in the rod 7 so as to cause rupture under the effect of a horizontal acceleration greater than a determined threshold , for example understood
entre 10 et 15 g.between 10 and 15 g.
La goupille 8, quant à elle, se fracture en cas d'accélération verticale dépassant un seuil dont la valeur peut, par exemple, être égale a la valeur The pin 8, for its part, fractures in the event of vertical acceleration exceeding a threshold whose value can, for example, be equal to the value
du seuil précité.of the aforementioned threshold.
La branche supérieure 4 présente, en face de la douille 6, un passage 10 se poursuivant par une bague 11 soudée sous la branche 4 et présentant un décrochement interne 12 réduisant le diamètre du passage vers le bas. Par l'orifice supérieur du passage 10, on introduit un manchon 13 dont la moitié inférieure The upper branch 4 has, opposite the bush 6, a passage 10 continuing with a ring 11 welded under the branch 4 and having an internal recess 12 reducing the diameter of the passage downwards. Through the upper opening of the passage 10, a sleeve 13 is introduced, the lower half of which
14 est extérieurement filetée et dont la moitié supé- 14 is externally threaded and of which the upper half
rieure 15 s'évase de façon conique vers le haut et comporte quatre fentes verticales 16 ouvertes vers upper 15 flares conically upwards and has four vertical slots 16 open towards
le haut.the top.
Au montagei l'extrémité supérieure de la tige 7 traverse le passage interne, de diamètre à peine During assembly, the upper end of the rod 7 crosses the internal passage, barely of diameter
supérieur, du manchon 13, en étant donc libre en trans- upper, of the sleeve 13, thus being free in trans-
lation par rapport au manchon. Les deux pièces 7 et 13 peuvent par contre être solidarisées en rotation par une goupille (non représentée) traversant une fente diamétrale de l'extrémité supérieure de la tige 7 et pénétrant dans deux fentes 16 diamétralement opposées relation to the sleeve. The two parts 7 and 13 can on the other hand be secured in rotation by a pin (not shown) passing through a diametrical slot of the upper end of the rod 7 and penetrating into two diametrically opposite slots 16
de la pièce 13.from Exhibit 13.
On visse alors un écrou 17 sur la partie inférieure 14 de la pièce 13 et, à partir du moment o l'écrou vient s'appliquer contre la face inférieure de la branche 4, la poursuite du vissage sollicite le manchon 13 vers le bas. Le rebord 12, coopérant avec la surface conique de la partie supérieure 15 du manchon, provoque alors le serrage de cette partie - 5 fendue autour de l'extrémité supérieure de la tige A nut 17 is then screwed onto the lower part 14 of the part 13 and, from the moment the nut is applied against the lower face of the branch 4, the continued screwing urges the sleeve 13 downwards. The rim 12, cooperating with the conical surface of the upper part 15 of the sleeve, then causes this split part - 5 to be tightened around the upper end of the rod
fracturable 7 qui se trouve ainsi bloquée. fracturable 7 which is thus blocked.
La tige fracturable forme ainsi une entretoise qui rigidifie parfaitement le support tant que les accélérations n'atteignent pas le seuil permettant le cisaillement de la tige 7 ou de la goupille 8. Par contre, en cas de cisaillement de la tige et/ou de la goupille, la pièce en U, 1, se déforme en encaissant l'énergie du choc, protégeant par là le matériel supporté. -6- The fracturable rod thus forms a spacer which perfectly stiffens the support as long as the accelerations do not reach the threshold allowing the shearing of the rod 7 or of the pin 8. On the other hand, in the event of shearing of the rod and / or of the pin, the U-piece, 1, is deformed by absorbing the impact energy, thereby protecting the supported material. -6-
